I've been through a number of mail services over the last few years and maileroo is a standout for me. Everything about it. The underlying service is great, the architecture is solid and its super reliable and delivery is fast. As well as that the UX for the interface is also really well crafted making it a pleasure to use. Beyond that the service levels are superb, fast and useful. Lastly, the price point is superb. It really is hard to fault Maileroo, I'd give it 6 stars out of 5 if I could

Very pleasant experience with Maileroo. We successfully migrated from Mailjet without any problems. The technical team was very helpful and listened to suggestions and created new features in a relatively short time.

I really like it. It is a new service, so there is always the possibility that as it grows, it might deteriorate over time, but my experience so far has been exceptional. The instructions for adding domains are clear and easy to follow, domain verification after adding the correct DNS records is very fast, the emails are sent promptly, and so far none of them have ended up in spam folders.

The support was really fast, and the whole process was very easy to set up. I requested an increase in the 100 emails/hour limit, and within a few minutes, the team had increased it. So far, so good.

I'm not a techie person or programmer, and this is my first time using an SMTP server. I was having some issues setting up one of my tools with maileroo's SMTP servers. A quick support chat inquiry led me to one of the co-founders who spent about an hour with me to solve my issue. In the end, it was all my own human error. We were able to fix the issue, but the best thing about the whole experience was how patient and pleasant Areeb was. Just a really great experience, especially for someone like me who isn't a developer or IT specialist.

Maileroo is easy to congifure the SMTP relay to send your transactional emails. It works perfectly. The SMTP plugin that you recommended did not work for me, but I had both problem using a free SMTP plugin. Also I was not able to understand how to use the API. I would like to be able to assigns sending limits per each domain. I only purchased I code because there was only 1 Tier listed. I might have stack 2 codes if I new the limits offer with 2 codes.

I was blown away by the customer support of Maileroo. I signed up for a free tier of their service because I had a client with simple but specific needs and it seemed like a perfect fit. However, since I was new to setting any of this up, the entire process was a learning curve for me.

We were searching for a new SMTP provider, after the one we were using raised the prices for the 3rd time - in 2 years. We Found Maileroo and couldn't be happier. Everything works smoothly, prices are top-notch, and their support is friendly and helpful.

I really like Maileroo for how it offers easy access to SMTP services with great reliability and service. The prices and SLA are excellent, and overall, everything just works perfectly. I also switched from Mailgun to Maileroo because of the better service it provides. The setup was super easy, taking only two minutes, which was a huge plus for me.
